I d like to have a computer for advice

The graphics card can be swapped out for an HD5750.

Pick the chassis, the first is to pick the material, it is recommended that the best case with steel plate is the best condition, emphasizing the cost performance of the case to buy the steel plate, the steel plate chassis is not recommended to buy, the steel plate is too thin will resonate, if the CPU radiator, graphics card radiator is relatively high-end, there may be a deformation of the motherboard due to insufficient steel plate support.

Secondly, look at heat dissipation and dust prevention. Basically, the current mid-range chassis has done both of these points better, and it is best to see that the fan position is 12cm, so that the fan will be quieter in the future. In the future, you can add your own dust filter, of course, if the chassis comes with it, it is better.

Other functions, I personally think that basically not many people use them, after all, computers are used to use, not everyone likes DIY so much. Just one point to mention here, if you are buying a chassis with a power supply underneath, you must consider whether the power cable is long enough. Most of the current low-end power supplies (less than 300 yuan) have not kept up with the trend of power supply, and it is likely that the cable is not long enough.

There is also the "motherboard back cable", which also requires the cable to be long enough, otherwise this function will be in vain. Of course, it can also be achieved by adding an "extension cord", but it is inconvenient to have one more connector after all, hehe, you will know it after trying it yourself.

It is not recommended to buy Jingdong**, **expensive, and the configuration is not reasonable.

1.Boxed CPUs also use a separate heatsink? If you don't overclock, it's completely unnecessary, so remove the overclocking Triple (PCCcooler) Red Sea Mini Multi-Platform CPU Cooler. The regular price of the boxed 2120 is 390, which is not as expensive as the 475.

2.The i3 2120 is equipped with a 460 graphics card, which is a bit wasteful, and the 460 does not perform at its best. HD is enough, such as Blaupunkt HD 6770 512MB GDDR5 Platinum Edition, 599 yuan.

But Jingdong ** may not be in stock, you can choose the GD5 version 6770 on Jingdong.

3.Dual-core CPU, power rated 300-350W is enough, there is no need to match it to 450W so high, it is used for quad-core and high-configuration graphics cards. However, this power supply is cheap and cost-effective, so it doesn't hurt to use it.

It's expensive, a lot of things can be saved.

Very good. The overall is ok. It's the CPU low.

It's all right, it mainly depends on what you do with it, this configuration is already very good.

Fortunately, this configuration is enough for me.
